Unmarked versions of the Meteor may been seen by using a data viewer. Unlike other gang cars in GTA 2, two versions of the unmarked Meteor exist instead of one. One features exposed equipment on the hood and trunk, while the other does not. Neither unmarked Meteors appear in game.
It isn't armored, and it's probably the fastest car in GTA2.

The Meteor's internal name, STRATOS, suggests the vehicle is based on the Lancia Stratos.
